Abstract
A communication structure and method which allows connection-like and connectionless communications to be provided on a multiplexed link is provided. The structure and method can make efficient use of available transmission capacity and/or network resources while providing both types of communication and hybrids. Connection-like communications can be provided by a channel having allocated transmission capacity dedicated to the communication while connectionless communication can be provided by a shared channel through which data can be transmitted to subscribers. In an embodiment, the shared channel transmits frames of packets addressed to one or more of the subscribers. The allocation of transmission capacity between the dedicated channels and the shared channel can be fixed, or can be managed to meet network or network operator requirements. The structure and method can also be managed by the network operator to permit prioritization of some communications over others. In another embodiment, two or more shared channels are provided.
Claims (17)
1. A communications structure for communicating between at least one network node and at least two subscriber stations through a multiplexed link, said structure comprising:
a plurality of dedicated channels, each dedicated channel having allocated to it a portion of the transmission capacity of said link to provide communication between said network node and one of said at least two subscriber stations; and a shared channel having allocated to it a portion of the transmission capacity of said link and wherein said shared channel is operable to transmit frames of packets from said network node to said at least two subscriber stations.
a plurality of dedicated channels, each dedicated channel having allocated to it a portion of the transmission capacity of said link to provide communication between said network node and one of said at least two subscriber stations; and a shared channel having allocated to it a portion of the transmission capacity of said link and wherein said shared channel is operable to transmit frames of packets from said network node to said at least two subscriber stations.
2. The structure according to claim 1 wherein said portion of the transmission capacity of said link allocated to said shared channel is fixed.
3. The structure according to claim 1 wherein said structure includes a preselected minimum number of said dedicated channels and said portion of the transmission capacity of said link allocated to said shared channel comprises the balance of said transmission capacity which is not occupied by said preselected number of said dedicated channels.
4. The structure according to claim 1 including at least two shared channels, each shared channel being operable to transmit frames of packets from said network node to said at least two subscriber stations.
5. The structure according to claim 4 wherein each of said at least two shared channels is operable to transmit said frames of packets to different ones of said at least two subscriber stations.
6. The structure of claim 4 wherein said balance of said transmission capacity is allocated unequally to each of said at least two shared channels.
7. The structure according to claim 3 wherein additional dedicated channels are created, as needed, by reallocating necessary transmission capacity of said link from at least one shared channels to such additional dedicated channels.
8. The structure according to claim 7 wherein said at least one shared channel has a preselected minimum transmission capacity and reallocation of transmission capacity from said at least one shared channel to said additional dedicated channels ceases before said transmission capacity allocated to said shared channels falls below said minimum transmission capacity.
9. The structure according to claim 1 wherein data for a subscriber station is transmitted from said network node via a combination of a dedicated channel and said shared channel, said dedicated channel providing a first data transmission rate and said shared channel providing an additional transmission rate, as needed, to accommodate transmission bursts in excess of said first data transmission rate.
10. The structure of claim 1 wherein at least one of said plurality of dedicated channels has a different amount of said transmission capacity allocated to it than does another of said plurality of dedicated channels.
11. The structure of claim 1 wherein said link is a radio link.
12. The structure of claim 11 wherein said radio link employs CDMA as a multiplexing technique.
13. A method of transmitting data from a network node to a plurality of subscriber stations over a multiplexed link, comprising the steps of:
(i) determining the requirements for a first data transmission intended for a subscriber station;
(ii) selecting the use of a dedicated channel or a shared channel to effect said first data transmission in accordance with said determined requirements; and (iii) if a dedicated channel is selected, obtaining a dedicated channel when available and transmitting said first data transmission thereon and if a shared channel is selected, transmitting said first data transmission on said shared channel in the form of data packets addressed to said subscriber station.
(i) determining the requirements for a first data transmission intended for a subscriber station;
(ii) selecting the use of a dedicated channel or a shared channel to effect said first data transmission in accordance with said determined requirements; and (iii) if a dedicated channel is selected, obtaining a dedicated channel when available and transmitting said first data transmission thereon and if a shared channel is selected, transmitting said first data transmission on said shared channel in the form of data packets addressed to said subscriber station.
14. The method of claim 13 wherein the determination in step (i) is made in consideration of the QoS requirements of said first data transmission.
15. The method of claim 13 wherein the determination in step (i) is made in consideration of the type of data to be transmitted.
16. The method of claim 13 wherein, if a dedicated channel is selected and no such dedicated channel is available, said first data transmission is transmitted on said shared channel.
17. The method of claim 13 where in step (ii), both a dedicated channel and a shared channel are selected, an amount of said first data transmission corresponding to the transmission capacity of said dedicated channel being sent thereon and the balance of said first data transmission being sent on said shared channel.
